As photoluminescence (PL) research evolves, so does the demand for sensitive instrumentation to measure increasingly weak PL signals. Besides photon-counting detectors and monochromators with good stray light rejection, the source used to excite the sample is a key component to consider when designing an experiment.

In this technical note, an Edinburgh Instruments FLS1000 Photoluminescence Spectrometer was used to acquire the fluorescence and phosphorescence spectra of a fluorescent emitter at 100 K.

Time-correlated single photon counting (TCSPC) is the method of choice for measuring fluorescence lifetimes due to its excellent time-resolution. TCSPC can be thought of as a very fast stopwatch with two inputs (Figure 1)...

In this technical note we explore Transient absorption (flash photolysis), which is a powerful tool to understand many photochemical properties and reactions, from measuring the energy levels and lifetimes of excited singlet and triplet states, to measuring electron and energy transfer rates of paired molecular systems, and even photocatalysis intermediates and products.

In this technical note we describe the operation of Batch Mode and demonstrate two examples where it is useful: temperature maps of anisotropy and measurements on multiple samples.
